HSK ultrasonic tool handle structure with automatic tool replacement function

Abstract

The invention discloses an HSK ultrasonic tool handle structure with an automatic tool replacement function. The HSK ultrasonic tool handle structure comprises an HSK tool handle, a retainer, a wireless power emitting end, a wireless power receiving end, an ultrasonic transducer and a pressing plate. A tool clamping portion is formed on the periphery of the end, close to the ultrasonic transducer, of the HSK tool handle and is located under the wireless power receiving end. The HSK ultrasonic tool handle structure is ingenious in design, a wireless power transmission mode is adopted, a series problems of abrasion and low rotation speed of spindles due to traditional sliding ring modes are effectively solved, and the operation stability of an ultrasonic motorized spindle is improved, and the structure has the advantages of high stability, high rotation speed, high precision and long service life; the wireless power receiving end is suspended on the motorized spindle through the retainer, dismounting and mounting are convenient, the HSK tool handle and the spindle are relatively independent, and convenience is brought to daily use and replacement; the tool clamping portion is located under the wireless power receiving end, automatic tool replacement is possible, and automatic tool handle replacement and placement of a tool changer are achieved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic tool holders, in particular to an HSK ultrasonic tool holder structure capable of automatic tool change. Background technique [0002] At present, some special materials are more and more widely used, such as glass, sapphire, silicon carbide, composite materials, etc. Due to the hard and brittle mechanical properties of these materials, the traditional processing technology cannot meet the processing accuracy requirements of these materials. At present, the industry adopts the ultrasonic energy-assisted method, combined with the high-speed rotation of the existing machine tools, to improve the machinability, processing accuracy and improve the life of processing tools for such hard and brittle materials. In ultrasonic-assisted machining, ultrasonic energy is the most critical parameter of the machining process, which plays a role in stimulating the atomic energy of the material and reducing th...

Problems solved by technology

[0003] However, the existing transducers and HSK ultrasonic tool holders are all designed with a split structure, which increases the complexity of the structure of the ultrasonic electric spindle, and the scope of use is narrow, and generally uses slip rings to transmit ultrasonic energy. The contact structure will have a
